Proudly caring for northern california, birthplace of pioneers. Good evening. Thanks for joining us. They were among the toughest elite athletes in the world. But it was their singleminded drive that ironically may have left some of them vulnerable to a sexual predator. Some women of team usa gymnastics say they were forced to endure psychological and physical abuse in the name of olympic glory and theyre now fighting back to protect the Young Athletes of the future. She will forever be one of the magnificent 7. At just 14, dominique mochianu helped team usa get gold in 1996. But her journey to olympic glory, she says, came with a backdrop of psychological abuse from her let me gend dear coaches. Bella and marta karoly. I was scared of getting in trouble all the time because they had this sense of control and fear in the gym. Reporter for years shes been a singular voice, speaking out against the karolys and the empire they helped build, usa gymnastics. Ive been speaking for ten years and people are finally listening. Reporter this week she testified on capitol hill. I have firsthand knowledge of how the culture set the stage for other atrocities to occur. It is a culture of fear, intimidation, humiliation. Reporter standing with her fellow champions jamie dantcher and Jessica Howard, saying that culture created an environment that allowed their Team Doctor Larry Nasser to sexually abuse them, and many others. I trusted usa gymnastics. But i was sexually abused, as were so many other athletes. Dr. Nasser abused me at the National Training center in texas. Worse, he abused me in my hotel room at sydney, the olympic games. Reporter nasser was the head physician for team usa gymnastics for 19 years. You can see him here after carrie injured her ankle in the 1996. Dr. Nasser acted as the good guy, supporting me emotionally and promising relief from the pain. Now i know he expertly abused me under the guise of treatment. Reporter the three former gymnasts shared their very personal stories with the Senate Judiciary committee to support landmark legislation that would help protect Young Athletes from sexual predators. Protecting all children in sports from abuse is paramount importance. That is why this bill is so vital. Reporter dr. Nasser has denied these allegations of sexual abuse. Usa gymnastics officials were invited to testify but declined, citing pending litigation. But in a Statement Given to the associated press, usa gymnastics says it cares deeply about the issues raised and supports the bill. Mochianu herself was not a victim of dr. Nassers alleged sexual abuse did and the karolys themselves have never been accused, she says her years working with them left emotional scars. If you were late to an event there was a chance you could get kicked out of the gym. Things were very, very stressful. Reporter she says her fate was in the hands of bella and marta karoly, known for their brusque style and uncompromising methods. They coached the likes of simone biles to greatness. You would see the winner, powers through everybody reporter for the lucky ones the road to olympic stardom led to the karoly ranch in texas. When dominique arrived there as a young teen it wasnt what she imagined. A lot of athletes werent smiling, werent happy. It just right away when i walked in the gym i felt like the sense of coldness. Reporter she says when gymnasts were injured they were pressured to keep training. As if you, the athlete, were weak if you spoke up and said, im hurting. You are not allowed to say, im hurting. And so that creates a cycle of psychological warfare in a way. I got humiliated. I was mortified. Reporter mochianu says this culture of shaming and fear was ultimately to blame for the recent allegations of sexual abuse against dr. Nasser. We were around a lot of adults that were kind of cruel. So it opened the door for a predator to start grooming and being your friend. And being nice to you. Hence enter dr. Nasser. He was the nice one. This environment created that open door for him to kind of know and zero in on who he could groom. Reporter jamie dantcher says it happened to her. He was helping me get to my olympic dream. Something ive been dreaming is about since i was 3 years old. I didnt even question it. Reporter she took home bronze at the 2000 games in sydney, a shining triumph. Behind it, she says, a painful trauma. He did touch my breasts underneath my tshirt. When he first did the procedure, well call it, i was 13 or 14. Reporter she says she met dr. Nasser shortly after making the national team, seeking treatment for back pain. He said that there is a procedure or a way to get my hips back in alignment when he would put his fingers into me vaginally. And i dont know how i wasnt uncomfortable, but just being a kid and being a little girl and being in such an intense environment, i was so miserable because i felt like i got in trouble every day for something else. I had no idea back then that he was doing something wrong. Reporter rhythmic gymnast Jessica Howard said she also didnt realize what was going on. Like i was so trusting. So it didnt even go through my head that this man could be hurting me. Reporter she told abc news she was willing to push through almost anything in order to become a threetime national champion. Howard recently shared her story with abcs linzie janis. You come from a an entire environment of silence and strength and doing what youre doing. Doing what youre told, obedience. And i just did what i was told. Id had extreme hip pain, like to the point where i would wake up in the morning unable to walk. So you showed up in your shorts and no underwear. Uhhuh. You laid on the table, what happened next . He began massaging kind of my quads and i. T. Bands. Then he got closer and closer, you know. To more intimate areas. And then he penetrated me. Reporter today, nasser was in a Michigan Court facing charges of criminal Sexual Conduct involving a victim under 13 years of age. The alleged victim wasnt a gymnast or a patient in his care. Its one of four different ongoing criminal cases against nasser involving underaged sexual misconduct, none of which are connected to his work with usa gymnastics. Nasser has pleaded not guilty to all charges. This guy is despicable, this guy is disgusting, and hes a monster. Reporter in total, more than 100 women and girls say they were victims of nasser. At least 60 of whom have filed civil complaints against him. I want him to spend the rest of his life in prison. The number of people that have come forward. The things that hes done are reprehensible. And an affront to basic human rights. And i believe that he deserves to be punished for what hes done. Reporter some, like dantcher, want to hold the karolys responsible. She filed a civil suit against them and other members of usa gymnastics. They created an atmosphere of intimidation, fear, control. We werent allowed to talk. They controlled what we ate. They controlled when we spoke. Reporter a spokesperson told abc news, the karolys vehemently deny the allegations against them and the existence of a toxic environment. They did not have any complaint knowledge of any complaint from anyone concerning any athletes alleged mistreatment by dr. Nasser until they learned of his dismissal from usa gymnastics during the summer of 2015. For mochianu, whos now a mother, its not just about justice for the past, its about changing the future. The way i look at it is, i cant change the past, i can change the future. I want to heal the future and be part of saving so many future athletes the angst and the pain that we all went through.

And what if this happened again . I was given warfarin in the hospital, but wondered, was this the best treatment for me . So i asked my doctor. And he recommended eliquis. Eliquis treats dvt and pe blood clots and reduces the risk of them happening again. Yes, eliquis treats dvt and pe blood clots. Eliquis also had significantly less major bleeding than the standard treatment. Both made me turn around my thinking. Dont stop eliquis unless your doctor tells you to. Eliquis can cause serious and in rare cases fatal bleeding. Dont take eliquis if you have an artificial heart valve or abnormal bleeding. If you had a spinal injection while on eliquis call your doctor right away if you have tingling, numbness, or muscle weakness. While taking eliquis, you may bruise more easily. And it may take longer than usual for bleeding to stop. Seek immediate medical care for sudden signs of bleeding, like unusual bruising. Eliquis may increase your bleeding risk if you take certain medicines. Tell your doctor about all planned medical or dental procedures. Eliquis treats dvt and pe blood clots. Plus had less major bleeding. Both made eliquis the right treatment for me. Ask your doctor if switching to eliquis is right for you.

But do they really work . Heres abcs chief business, economics and Technology CorrespondentRebecca Jarvis. Reporter from late nights out, to Early Morning meetings. 30yearold Erin Finnegan this is the secret to her work hard, play hard lifestyle. Im bicoastal. Im a lot of times traveling. This is the only one that i take with me. Reporter nootropics, known as smart trucks, supplements some claim enhance brain function. Helping improve memory, focus, maybe making you brilliant.

Scale of 1 to 10, how much smarter do you feel on nootropics . 10. Reporter startups like nootrabox cofounded by jeff wu are helping rebrand smart drugs as part of the multi billion dollar supplement industry. If theres one smart person in the world, great, we have another einstein. If everyone was super smart, theres like an exponential amount of innovation going on. Reporter but as these supplements become more mainstream, some doctors are questioning whether the claims are too good to be true. What are some of the concerns about nootropics . The lack of controlled trials. The lack of rigorous scientific research. The lack of studies that actually try to study all of these different types of nootropics in certain combinations. Reporter nootropics stacks, mixes of individual components, can include anything from caffeine and lthanine to herbal supplements to pirazapam. How did you get involved in nootropics . I wanted to be smarter, i grew up very competitive and wanting to be the best version of myself possible. Reporter four years ago jeff was working at a Venture Capital firm when he started digging around the internet and experimenting. Tinkering with things from laboratories from china.

You wanted to be a better human . I think we all want to be better versions of ourselves. I think thats one of the distinctive factors of being human. Reporter its a good pitch. But shark tank didnt bite when jeff and cofounder Michael Brant brought it on the show. It scares the hell out of me. Ive tried nootropics. Thats what people use to go on 48hour coding binges. At the end of the day youre left with a headache, lack of recall sometimes. Im worried about the longterm consequences so im out. Reporter although theyre said to alter brain function, nootropics are not labeled a drug, but as a type of dietary supplement. Meaning they dont need fda approval. Nootropics are not fda approved everything we do use is fda, generally regarded as safe, which is the highest level of safety the fda gives for all things one can consume. Does it ever concern you the mixture of these things could make them unsafe . No, because thats where our science team, which consists of actually practicing doctors and ph. D. S, walk through that and validate any crossindications. Despite this confidence, some caution nootropics could have side effects, many citing lack of studies about longterm impacts. There are also interactions. There may be one of the many ingredients on there that may react with Blood Pressure medicines or something else. Thats why we always recommend discussion and approval by the treating physician. Reporter its not just the tech world clamoring for these little life optimizers. Entrepreneur Erin Finnegan swears by them. It does sustain the speed im going right now and the many things id have to take a couple of things off my plate if i wanted to keep going on without them.

On a stressful day she says shell take eight to ten pills. Before i found the nootrovox, i had 12 different ones that i was taking. Those 12 different ones are summed up in these really well. Reporter and there are plenty of others like her. The problem is again, we dont have all the data to support whether or not these individual agents or in combination work to improve brain health. Going from this to this reporter 29yearold eric matsner created his company nootroo after becoming fascinated with what he discovered online. If youre to be a bio hacker, its about finding the right pills and the right brand. Reporter he shows us his morning routine, over 60 supplements a day. I do three or four handfuls every morning. Reporter are smart drugs the future . Many here seem to think so. Were talking about a new type of science, were taking these things into our own hands but also to proactively try and go from baseline to above.
